As a math leader, I help teach teachers as well as students. The Hands-on Standards books have been a wonderful resource for my school. They encourage teachers to use different manipulatives in their classrooms in an easy to use format. The photos really help show what the students are to be doing. This is great for teachers new to the profession or those who need a visual to understand the process! The books were so helpful, I got one for all K-5 teachers!
